VENTILATOR.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed March 2, 1914. Serial No. 821,951.

I '0 all whom it may concern Be it known that I, ALBERT L. AnAMs, acitizen of the United States, residing at Cedar Rapids, in the county ofLinn and State of Iowa, have invented a new and useful Ventilator, ofwhich the following is a specification.

The present invention relates to improvements in ventilators'moreespecially adapted for chicken coops or brooders, one object being theprovision of a novel form of ventilating means, whereby the desiredcirculation without draft may be had within the coop or brooder.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of What is claimed without departing from the spirit of theinvention.

In the drawingsFigure 1 is a front elevation of the complete coop orbrooder with the door closed and the chick outlet opened. Fig. 2 is avertical central sectional view through the complete coop or brooder,the ends of the crossed members of the support being foreshortened. Fig.3 is a bottom plan view of the ventilating cover and its support removedfrom the brooder. Fig. 4 is a section through the body and lower rim ofthe brooder showing the position of the door. Fig. 5 is a cross sectiontaken on line 55 of Fig. 1.

Referring to the drawings, the numeral 1 designates the main closurewhich is made from a single sheet of metal in a circular dome-shapedform, the lower edge 2 being rolled to incase a reinforcing rod 3. Anenlarged opening a is formed in the lower edge of the inclosure abovethe rim 3 while the chick outlet 5 is formed as illustrated in Fig. 1,with the apertures 6 which provide for the necessary light within thecoop or brooder. A plurality of lips or tangs 7 are out and pressedoutwardly from the body of the material to provide the ventilatingopenings 8 adjacent the lower rim of the inclosure. Any number of thesemay be provided as may be found necessary.

The bottom 9 is formed of a disk of metal and is provided with a crimpedrim 10 which when properly positioned as shown in Fig.

2 has a resilient outward tension against the lower rim of theinclosure, so as to maintain the bottom in proper sealing position evenwith the weight of the chicks thereupon and the brooder elevated abovethe ground. In order to prevent any undue flexing of the bottom and tomaintain the upper surface level, a coiled spring 11 is connectedcentrally thereof and is of sufficient length to engage the ground orsurface supporting the brooder at the same time that the lower edge ofthe rim 10 and the lower rim of the inclosure 1 are in contacttherewith. The spring 11 also provides a means whereby the bottom may bemanipulated to be removed or placed in position, as illustrated in Fig.2.

The inclosure l is made of such shape that when shipped one may benested within another and thus save shipment space while the bottoms 9are also constructed in a similar manner for nesting, it simply beingnecessary in assembling the present device, that the bottom 9 be placededgewise within the lower edges of the coop and then turned to assumethe position as shown in Fig. 2.

In constructing the present brooder, the body 1, as before stated, ismade from a single sheet of metal, the same being preferably galvanizedso as to withstand the elements, a plurality of corrugations 16 beingformed in one edge thereof so as to impart the shape as illustrated inFigs. 1 and 2 to the complete sheet so that when the edges thereof areoverlapped and connected (not shown), an opening 17 may be providedcentrally at the top of the coop. The grooves or corrugations 16therefore provide a plurality of channels leading to and from theopening 17, and in order to provide a means for closing the opening tothe desired degree and yet at the same time cooperate with thecorrugations 16 to provide a plurality of ventilating channels a conicalcover 24 is employed. This cover 24, as clearly lllIlS trated in Fig. 2,carries the handle 25 provided with the screw threaded shank 21, thelock nuts 22 and 23 being disposed thereupon to lock the same to thecover.

In order to adjustably support the cover 24 relatively to the opening 17and the upper edge of the inclosure 1, the two plates 18 and 19 areprovided and have their terminals fast to the outer surface of theinclosure 1 to the exterior surface of the corrugated portion thereof,said plates belng provided with alined threaded apertures 20 for thereception of the threaded shank 21 which by the rotation of the handle25 imparts rotation to the cover 24: and through the threaded connectioncauses the cover 24: to be moved to and from the inclosure 1 andconsequently decreases or increases the space adjacent the corrugatedportion and consequently the ventilating space at the top of the coop orbrooder. The cover 24: is of such a size as to overlap the edges of theopening 17 to prevent the intrusion of rain so that the present brooderwill keep the chicks therewithin in the proper dry and sanitarycondition and at the same time permit of the ventilating of thecoop orbrooder without undue draft upon the chicks. In order to provide aclosure for the opening l and also that the same may be placed over toclose the chick outlet 5 and the light admitting aperture 6, a curvedplate 12 which constitutes the door and is provided with the operatingknob or handle 13 is slidably mounted concentrically of the exteriorface of the inclosure 1 so that its respective upper and lower edgescooperate with the cleats 14-11 and the water excluding overhangingledge 15 which is secured to the exterior surface of the coop orinclosure and as particularly illustrated in Figs. 1 and 4. By thismeans, the door 12 may be moved to assume the dotted line position so asto permit the ready access to the interior of the coop for cleaning orfor removing the chicks therefrom.

lVhat is claimed is:

1. A metallic coop or brooder, the body of which is dome-shaped and isprovided with a central ventilating opening through the apex thereof, aconical cover for the opening, and cooperating means carried by the coveand body to adjustably mount the cover for movement to and from thebody.

A metallic coop or brooder, the body of which is dome-shaped and isprovided with a central ventilating opening through the apex thereof, aconical cover for the opening, cooperating means carried by the coverand body to adjustably mount the cover for movement to and from thebody, the body of the brooder adjacent the opening being convoluted toprovide a plurality of ventilating channels a portion of which isoverlapped by the periphery of the cover when the cover 1s in closingposition.

3. A metallic coop or brooder, the body of which is composed of a singlesheet of metal one edge of which is convoluted to produce a taperingefii'ect and also to provide a ventilating opening at the apex of thecoop or brooder, a conical cover for the opening, and cooperable meanscarried by the cover and spanning the opening and attached to the bodyof the coop or brooder for adjustably connecting the cover for movementsto and from the convoluted edge of the body.

4:. A metallic coop or brooder, the body of which is composed of asingle sheet of metal one edge of which is convoluted to produce atapering effect and also to provide a ventilating opening at the apex ofthe coop or brooder, a conical cover for the opening, cooperable meanscarried by the cover and spanning the opening and attached to the bodyof the coop or brooder for adjustably connecting the cover for movementsto and from the convoluted edge of the body. anda handle carried by thecover for rotating the same to adjust it and also to provide a means forcarrying the coop or brooder.

A metallic coop or brooder, the body of which is dome-shaped andprovided with a central ventilating opening through the apex thereof, aconical cover for the opening, a bracing plate connected to the upperportionof the body and disposed diametrically of the opening thereof, athreaded stem adjustably connected thereto, and a conical coverconnected to the threaded stem for forming a ventilating closure for theopening. 1

6. Anietallic coop or brooder, the body of which is composed of a singlesheet of metal one edge of which is convoluted to produce a taperingeffect and also to pro vide a ventilating opening at the apex of thecoop or brooder, a plate connected across the opening, a threaded stemadjustably connected to the plate, and a conical cover connected to thethreaded stem for forming a ventilating closure for the opening.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.
